5 Claims.

Introduction The present invention relates to dispensers and moreparticularly to dispensers adapted for attachment to a household watersupply so as to mix various liquids with the water.

The purpose of the present invention is to provide a device of thisnature that can be attached to any household water outlet so as to mixand dispense liquids such as water softeners, soaps, perfumes, andantiseptics by the action of the water flowing from the outlet.

Applicants development Accordingly, the present invention comprises of adispensing and mixing device adapted for attachment to a water supplyand includes means whereby the pressure of Water flowing into the deviceis adapted to withdraw the liquid to be dispensed with the water in anypredetermined solution strength from a supply receptacle supported bythe device.

More specifically, a preferred construction of a dispenser according tothe invention comprises of a main dispenser body having a pair ofbulbous end portions connected by a substantially cylindrical joiningportion. One of the end portions is formed so as to have an openingpassing through the portion from top to bottom so as to constitute aliquid passage with the upper portion of the opening enlarged so as toprovide a main inlet chamber adapted to fit over the end of a householdtap.

Preferably, a pair of resilient washers are mounted in this chamber withthe inner diameter of the washers slightly smaller than the outside ofthe top so as to retain the dispenser firmly in engagement on the top byfrictional contact.

A further enlargement of the passage coextensive with and slightlysmaller than the main inlet chamber provides an annular seat adapted toreceive a liquid restricting member that extends from the main inletchamber into a still further enlargement of the passage adapted toprovide a mixing chamber. The liquid restricting member comprises of acylindrical body having an outstanding annular head adapted to fit inthe chamher seat and includes an opening through the body that tapersfrom a comparatively wide opening in the head to a comparatively narrowopening at the end of the body so as to eifect an increase in the watervelocity discharged from the restricting member when the device is inoperation. The end portion of the passage extending from the mixingchamber to the outside of the end portion is also tapered but in theopposite direction, the smaller opening being disposed at the chamberwith the larger openin at the outer surface to provide an unrestrictedoutlet. As the restricting member extends to adjacent the bottom of themixing chamber and the lower opening in this member is slightly smallerthan the outlet opening leading from the chamber, the increased velocityof the water passing through the member and out of the outlet passagecreates a suction.

The other end portion of the dispenser is recessed so as to provide aninlet chamber for the soap or other fluid that is to be dispensed and ispreferably tapped so as to receive and retain a threaded fluid supplyreceptacle, for example, a bottle or the like.

An opening is provided through the joining portion so as to provide apassage connecting the mixing chamber of one end portion with the liquidreceiving chamber of the other portion and a control valve is providedin this passage so that the right amount of liquid is allowed to bedrawn from the liquid receiving chamber and supply so as to produce thedesiredsolution strength.

In an alternative construction the body end portion containing themixing chamber is provided with a cylindrical extension projecting fromthe lower end so as to provide a means of attaching a hose or conduit,for example, a dish washing attachment.

Detailed description Having thus generally described the nature of theinvention, particular reference will be made to the accompanyingdrawings, and in which:

Figure 1 is a front view in perspective elevation of a preferred form ofdispensing device constructed according to the invention as it may beconnected to a water supply.

Figure 2 is a section of Figure 1 along the line 2-2 illustrating theconstruction in more detail.

Figure 3 is a section of Figure 1' along the line 3-3 illustrating thecontrol valve arrangement.

Figur 4 is a front view of a portion of an alternative form ofdispenser, corresponding to Figure 2, and illustrating a construction ofthe dispenser outlet adapting it for connection by a hose or conduit.

With particular reference to the drawings, the dispenser comprises of amain body having a pair of bulbous end portions 19 and 12 connected by asubstantially cylindrical joining portion l4. In the preferredconstruction illustrated the end portion l8 and the joining portion [4are made as being in one piece with the end portion l2 thread The upperportion of the opening [8 is enlarged to provide a main inlet chamber 22and recesses 24 are provided in the walls of the chamber 22 so as toreceive and retain a pair of resilient washers 28.

The resilient washers 26 preferably have an inside diameter slightlysmaller than the usual outside diameter of the tap A so as to retain thedispenser firmly on the tap by frictional engagement. Coextensive withthe chamber 22, a second cavity or enlargement of the passage I8provides a seat 30 and a third enlargement of the passage [8 providedbelow the seat 30 provides a mixing chamber, 32. A liquid restrictingmember 34 is mounted in the seat 30 with a portion extending into themixing chamber 32. The liquid restricting member 34 includes acylindrical body 31 with an outstanding annular head 38 adapted to fitin the seat 30 with the body 31 fitting in the passage [8 and extendingdownwardly to adjacent the bottom of the chamber 32. An opening 40 isprovided in the member 36 that tapers from a comparatively wide opening39 adjacent the annular head 38 to a comparatively narrow opening 4| atthe end of the body 31.

The end of the passage l8 extending from the bottom of the chamber 32 tothe outer surface of the end portion is also tapered from acomparatively narrow opening 42; at the mixing chamber 32 to acomparatively wide opening 43 forming the outlet. As the restrictingmember 34 extends to adjacent the bottom of the mixing chamber 32 andthe lower opening 4| in the member 34 is slightly smaller than theopening 42 leading from the chamber 32, the increased velocity of thewater passing through the member 34 and out of the outlet passagecreates a suction adapted to draw the liquid to be dispensed into themixing chamber 32, where it is mixed and dispensed with the water.

The other end portion 12 includes a recess pro viding an inlet chamber56 adapted to receive the liquid that is to be dispensed. Preferably,the upper portion of the recess 56 is tapped and a supply source ofliquid attached, as for example, a bottle B of liquid soap or the like,as is shown in Figure 2. The end portion l2 includes a suitably threadedextension 52 adapted for threadably engaging the tapped end 54 of thejoining section [4 and an opening is provided through the extension 52and the joining section l4 so as to constitute a liquid delivery passage56 from the inlet chamber 50 to the mixing chamber 32. A small opening60 leading into the inlet chamber 50 is provided in the end portion [4so as to allow air to replace the liquid as it is withdrawn from thechamber 50. A control valve 52 is provided in the passage 56 to controlthe flow of liquid from the chamber '50.

In use, the flow of the water from the tap A is directed into therestricting member 34 and due to the particular construction of thismember and its position relative to the opening 42, the suction createdin the mixing chamber 32 draws liquid through the passage 56 from thechamber 50 and mixes the liquid intimately with the water as it flowsfrom the outlet 43.

In an alternative construction as illustrated 4 in Figure 4, the endportion I I0 is provided with a cylindrical extension 10 so as toprovide a means of connecting a hose or conduit, for example, adishwashing attachment C as illustrated.

A dispenser constructed in accordance with the invention can be placedon a household tap or other outlet with the container B filled withliquid soap or other cleansing fluid and can be left in position whilethe tap is in normal use. When it is desired to add soap to the waterthe control valve 62 is opened allowing the soap to be drawn into themixing chamber and dispensed with the water from the outlet.
